(II) technical scheme
In order to solve the technical problems, the invention adopts the following technical scheme:
a plastic pipe straightening treatment method comprises the following steps:
step one, cleaning the inner side wall and the outer side wall of the plastic pipe.
And step two, immersing the sponge block into lubricating oil, then penetrating the sponge block through the plastic pipe, and coating the lubricating oil on the inner side wall of the plastic pipe.
And step three, straightening the plastic pipe by adopting a plastic pipe straightening device.
And step four, cleaning the inner side wall of the straightened plastic pipe to remove the residual lubricating oil.
And step three, the plastic pipe straightening device comprises a water tank with a rectangular cross section, and the top surface of the water tank is provided with an opening. The distance between two opposite side walls of the water tank is greater than the length of the straightened plastic pipe, the corresponding positions on the two side walls are provided with sliding grooves in the vertical direction, and the sliding grooves extend to the top of the side walls of the water tank. Sliding fit has the slider in the spout, and slider one end stretches out the lateral wall of basin and fixedly connected with is on a parallel with the mounting panel of basin lateral wall, and articulated on the mounting panel have the pivot of horizontal direction, and the axis of pivot is on a parallel with the lateral wall of basin. An inserting rod perpendicular to the rotating shaft is fixedly installed on the rotating shaft, and the diameter of the inserting rod is equal to the inner diameter of the plastic pipe to be straightened. A guide groove coaxial with the inserted bar is formed in the inserted bar along the length direction of the inserted bar, an opening of the guide groove is located on the end face of the inserted bar, and a sliding column is in sliding fit in the guide groove. An elastic straight rod coaxial with the inserted bar is fixedly arranged on the end surface of the slide column close to the opening of the guide groove along the length direction of the inserted bar. And the other end surface of the sliding column is fixedly connected with one end of a first spring, and the other end of the first spring is fixedly connected with the inner end surface of the groove of the guide groove. When the sliding blocks on the two side walls of the water tank are positioned on the same horizontal plane and the two elastic straight rods are both in a horizontal state, the axes of the two elastic straight rods are overlapped. The end parts of the two elastic straight rods are respectively and fixedly provided with a first magnet block and a second magnet block which are matched with each other.
The limiting post is vertically matched with the limiting post in the sliding groove in a sliding mode, the limiting pin capable of stretching out and drawing back is installed at the top of the limiting post, and the pin hole matched with the limiting pin is fixedly installed on the top face of the side wall of the water tank. A plurality of heating wires are uniformly arranged in the bottom plate of the water tank, and a water inlet is formed in the side wall of the water tank. The concrete method in the third step is as follows: insert the spout with spacing post in, insert the round pin downthehole with the spacer pin, fix spacing post, and then fix the slider. Injecting water into the water tank through the water inlet; the water in the water tank is heated by the heating wire. The plastic pipe to be straightened is placed in the water tank to be heated for a period of time, and then the first magnet block and the second magnet block are pushed to drive the elastic straight rod and the sliding column to slide inwards along the guide groove to compress the first spring until the first magnet block and the second magnet block enter the guide groove. The ends of the two insert rods are plugged into the two ends of the plastic pipe to be straightened, the sliding column and the elastic straight rod slide outwards along the guide groove under the action force of the first spring, and the first magnet block and the second magnet block are driven to be close to each other in the plastic pipe. The attractive force is gradually increased in the process that the first magnet block and the second magnet block approach each other, and the first magnet block and the second magnet block are finally adsorbed together. Because the plastic pipe is in a bending state, after the first magnet block and the second magnet block are adsorbed together, the elastic straight rod is in the bending state. When the elastic straight rod is in a bent state, the elastic straight rod can generate large internal stress, and the internal stress enables the elastic straight rod to have the tendency of recovering the original shape. Because the first magnet piece and the second magnet piece of elasticity straight-bar one end mutually support and can't remove together, so elasticity straight-bar can exert the revolving force to the inserted bar through the traveller of the other end. The inserted bar gradually transits to the horizontal state under the action of the rotating force, and in the process, the inserted bar gradually slides towards the inside of the plastic pipe and enables the plastic pipe to deform until the axes of the two elastic straight bars recover to the linear state, namely the two inserted bars reach the horizontal state and the axes of the two inserted bars recover to the coincident linear state. Because the inserted bars and the inner side wall of the plastic pipe to be straightened are mutually matched, when the axes of the two inserted bars are restored to be in a superposed linear state, the axis of the plastic pipe also reaches a linear state, and the straightening of the plastic pipe is completed. After the straightening is finished, the limiting pin is withdrawn from the pin hole, and the limiting column is withdrawn from the sliding groove. And lifting the slide block upwards until the plastic pipe is taken out of the water tank. The inserted bar is pulled out from the two ends of the plastic tube.
As a preferable technical scheme of the invention, two parallel limiting plates are vertically and fixedly arranged on the upper surface of the water tank bottom plate. The two limiting plates are positioned on two sides of the inserted bar, and the distance between the two limiting plates is equal to the outer diameter of the plastic pipe to be straightened. The plastic pipe straightening device has the advantages that in the straightening process of the plastic pipe, the plastic pipe deforms along the vertical direction under the limiting effect of the limiting plate, and the straightening precision is improved.
As a preferred technical scheme of the invention, a plurality of supporting plates are uniformly arranged on the upper surface of the water tank bottom plate between the two limiting plates. Vertical fixed mounting has the second spring in the backup pad, and the top fixed mounting of second spring has articulated frame, and the last normal running fit of articulated frame has the gyro wheel of mutually supporting with the lateral wall of waiting to straighten the plastic tubing. In the straightening process of the plastic pipe, the roller is abutted to the outer side wall of the plastic pipe under the action force of the second spring and slides relative to the outer side wall of the plastic pipe, so that the action force in the vertical direction is generated on the plastic pipe, and the plastic pipe is promoted to recover more quickly.
As a preferred technical scheme of the invention, the outer circumferential surface of the inserted rod is uniformly provided with balls, and the balls are in rolling fit with the inner side wall of the plastic pipe to be straightened. When the plastic pipe is straightened and the plastic pipe and the inserted rod slide relatively, the rolling balls and the plastic pipe generate rolling friction, and damage to the interior of the plastic pipe is avoided.
As a preferable technical solution of the present invention, the first magnet block includes a circular magnet block fixedly mounted at an end of the elastic straight rod and coaxial with the elastic straight rod, and a semi-cylindrical magnet block perpendicular to the circular magnet block is fixedly mounted along an edge of the circular magnet block on an end surface of the circular magnet block away from the elastic straight rod. A plurality of limiting grooves are formed in the inner side wall of the semi-cylindrical magnet block along the length direction of the semi-cylindrical magnet block.
As a preferable technical solution of the present invention, the second magnet block includes a cylindrical magnet block fixedly mounted at an end of the elastic straight rod and coaxial with the elastic straight rod. A plurality of rolling balls are uniformly arranged on the outer circumferential surface of the cylindrical magnet block, and the rolling balls are in rolling fit with the limiting grooves. When the sliding blocks on the two side walls of the water tank are positioned on the same horizontal plane and the two elastic straight rods are positioned in a horizontal state, the axes of the circular magnet block and the cylindrical magnet block are superposed. When the first magnet block and the second magnet block are adsorbed together, the rolling ball is positioned in the limiting groove. When the inserted bar needs to be pulled out from the two ends of the plastic pipe after straightening, rolling balls and the limiting grooves generate rolling friction, and compared with the situation that the cylindrical magnet block and the semi-cylindrical magnet block are directly attached together, the rolling ball type plastic pipe straightening machine has smaller friction force, and is convenient for separation of the first magnet block and the second magnet block and separation of the inserted bar and the plastic pipe.
As a preferable technical scheme of the invention, the length of the inserted bar is not more than half of the length of the plastic pipe to be straightened, and the length of the elastic straight bar is not more than the length of the inserted bar, so that the inserted bar can be easily inserted into the plastic pipe.

The other end surface of the sliding column 8 is fixedly connected with one end of a first spring 10, and the other end of the first spring 10 is fixedly connected with the inner end surface of the guide groove 7. When the sliding blocks 3 on the two side walls of the water tank 1 are in the same horizontal plane and the two elastic straight rods 9 are in the horizontal state, the axes of the two elastic straight rods 9 are overlapped. The end parts of the two elastic straight rods 9 are respectively fixedly provided with a first magnet block 11 and a second magnet block 12 which are matched with each other.
A limiting column 13 is vertically matched in the sliding groove 2 in a sliding manner, a telescopic limiting pin 14 is installed at the top of the limiting column 13, and a pin hole 15 matched with the limiting pin 14 is fixedly installed on the top surface of the side wall of the water tank 1. A plurality of heating wires 16 are uniformly arranged in the bottom plate of the water tank 1, and a water inlet 17 is arranged on the side wall of the water tank 1.
In this embodiment, two parallel limiting plates 18 are vertically and fixedly installed on the upper surface of the bottom plate of the water tank 1. The two limit plates 18 are positioned at two sides of the inserted rod 6, and the distance between the two limit plates 18 is equal to the outer diameter of the plastic pipe to be straightened.

In this embodiment, the first magnet block 11 includes a circular magnet block 111 fixedly mounted at an end of the elastic straight rod 9 and coaxial with the elastic straight rod 9, and a semi-cylindrical magnet block 112 perpendicular to the circular magnet block 111 is fixedly mounted along an edge of the circular magnet block 111 on an end surface of the circular magnet block 111 away from the elastic straight rod 9. The inner side wall of the semi-cylindrical magnet block 112 is provided with a plurality of limiting grooves 113 along the length direction.
In this embodiment, the second magnet block 12 includes a cylindrical magnet block 121 fixedly mounted on the end of the elastic straight rod 9 and coaxial with the elastic straight rod 9. A plurality of rolling balls 122 are uniformly arranged on the outer circumferential surface of the cylindrical magnet block 121, and the rolling balls 122 are in rolling fit with the limiting groove 113. When the sliding blocks 3 on the two side walls of the water tank 1 are in the same horizontal plane and the two elastic straight rods 9 are in the horizontal state, the axes of the circular magnet block 111 and the cylindrical magnet block 121 are overlapped. When the first magnet block 11 and the second magnet block 12 are attracted together, the rolling ball 122 is located in the limiting groove 113. When the inserted bar 6 needs to be pulled out from two ends of the plastic tube after straightening, the rolling balls 122 and the limiting grooves 113 generate rolling friction, and compared with the situation that the cylindrical magnet block 121 and the semi-cylindrical magnet block 112 are directly attached together, the rolling friction force is smaller, and the separation of the first magnet block 11 and the second magnet block 12 and the separation of the inserted bar 6 and the plastic tube are facilitated.

The specific method in the third step in this embodiment is: the limit post 13 is inserted into the chute 2, the limit pin 14 is inserted into the pin hole 15, the limit post 13 is fixed, and the slide block 3 is further fixed. Water is injected into the water tank 1 through a water inlet 17; the water in the water tank 1 is heated by the heater wire 16. The plastic pipe to be straightened is placed in the water tank to be heated for a period of time, and then the first magnet block 11 and the second magnet block 12 are pushed to drive the elastic straight rod 9 and the sliding column 8 to slide inwards along the guide groove 7 to compress the first spring 10 until the first magnet block 11 and the second magnet block 12 enter the guide groove 7. The ends of the two insert rods 6 are plugged into two ends of the plastic pipe to be straightened, the sliding column 8 and the elastic straight rod 9 slide outwards along the guide groove 7 under the action of the first spring 10, and the first magnet block 11 and the second magnet block 12 are driven to be close to each other in the plastic pipe. The attractive force gradually increases as the first magnet block 11 and the second magnet block 12 approach each other, and is finally attracted together. Because the plastic pipe is in a bent state, after the first magnet block 11 and the second magnet block 12 are adsorbed together, the elastic straight rod 9 is in a bent state. When the elastic straight rod 9 is in a bent state, the elastic straight rod 9 can generate large internal stress, and the internal stress enables the elastic straight rod 9 to have a tendency of recovering the original shape. Since the first magnet 11 and the second magnet 12 at one end of the elastic straight rod 9 are engaged with each other and cannot move, the elastic straight rod 9 applies a rotational force to the insertion rod 6 through the sliding column 8 at the other end. The inserted bars 6 gradually transit to the horizontal state under the action of the rotating force, and in the process, the inserted bars 6 gradually slide towards the inside of the plastic pipe and enable the plastic pipe to deform until the axes of the two elastic straight bars 9 return to the linear state, namely the two inserted bars 6 reach the horizontal state and the axes of the two inserted bars 6 return to the coincident linear state. Because the inserted bars 6 are matched with the inner side walls of the plastic pipes to be straightened, when the axes of the two inserted bars 6 are restored to be in a superposed linear state, the axes of the plastic pipes also reach the linear state, and the straightening of the plastic pipes is completed. After the alignment is completed, the stopper pin 14 is withdrawn from the pin hole 15, and the stopper post 13 is withdrawn from the slide groove 2. The slide 3 is lifted upwards until the plastic tube is taken out of the water bath. The inserted bar 6 is pulled out from the two ends of the plastic tube.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
